My vote is for a solution that doesn't add to that burden.  Most of the output is just distracting, but then on the other hand one does want to get some sense that the build is making progress.  It would be really nice, I think, to get just one over-printed line that shows what directory is being worked on and that newlines are generated only by error, warning, and perhaps informational messages.

In the "normal" case (--enable-mm is present and mm is supported, and --enable-mm is not present and mm support isn't) the build system would stay quiet.

If mm support for a bsp isn't there could we just give a message saying it's not supported and have configure switch the option to --disable-mm?  That would eliminate a the path to test...
